Metasurface absorber for millimeter waves: a deep learning-optimized approach for enhancing the isolation of wideband dual-port MIMO antennas.

In this communication, the concept of metasurface absorber is utilized to enhance the isolation in the dual port multiple-input multiple-output (MIMO) antenna specially designed for a wideband millimeter wave operation. The frequency of operation of the designed module is 32.5-42.

Metasurface inspired printed dual‑port MIMO antenna system with LP to CP conversion features for millimeter wave n260 band applications.

A cutting-edge antenna system has been developed for new radio (NR) millimeter wave operating from 36.0 to 40.0 GHz frequency range 2 (FR 2) n260 band applications.

Circularly polarized printed dual port MIMO antenna with polarization diversity optimized by machine learning approach for 5G NR n77/n78 frequency band applications.

In this communication, a planar dual port multiple input multiple output antenna of size 1.2λ × 0.6λ × 0.

Efficient graphene-based circularly polarized MIMO antenna for THz applications.

In this paper, a graphene-based (MIMO) antenna is designed and examined. Two unique properties of the proposed terahertz (THz) MIMO antenna are (1) circular polarization is achieved through an asymmetrical cross slot, etched over the graphene patch; and (2) a bidirectional radiation pattern is achieved through oppositely oriented identical antenna ports. Mutual coupling between the antenna ports is less than -35.

Biotic control of harmful algal blooms (HABs): A brief review.

The water bodies, mainly coastal and lake, remain tainted worldwide, mostly because of the Cyanobacteria harbored in Harmful Algal Blooms (HABs). The main reason for the flourishing of blooms depends on the eutrophication. Blooms could be toxic as well as non-toxic, depending on the bloom-forming species.

Use of water quality index and multivariate statistical techniques for the assessment of spatial variations in water quality of a small river.

Rapid urban development has led to a critical negative impact on water bodies flowing in and around urban areas. In the present study, 25 physiochemical and biological parameters have been studied on water samples collected from the entire section of a small river originating and ending within an urban area. This study envisaged to assess the water quality status of river body and explore probable sources of pollution in the river.
